Can anyone help. I was recently highjacked by Antivirxp08, im not sure where
it came from, but I got the screen of death. It also prevented me from
uninstalling the program from "Add and Remove Programs". After a few hours
of reseach on the net, i did manage to get it removed from my system, however
when i came to shut down my my, i am now presented with the follwoing message.

STOP: c000021a {Fatal System Error}
The Windows Logon Process system process terminated unexpectedly with a
status of 0x00000000 (0x00000000 0x00000000).
The System has been shut down.

I carried out an upgrade hoping this would resolve the issue, but apparantly
not. I have all the upto date patches and service pack 3 for XP Pro. There
doesn't seem to be anything written in my events log, however this could be
because of the upgrade. I have done some searches on this probem and i found
some references to the c000021a problems, but nothing matching the same
status code i am recieving. I have tried using regcure and have run the
microsoft malicious software tool, neither have found anything. I really
don't want to have to reinstall windows xp again. So if anyone knows what
this message refers to or possibly have had this before and rectified this, i
would be grateful for you help.

Thanks

This occurs when Windows switches into kernel mode and a user-mode
subsystem, such as Winlogon or the Client Server Runtime Subsystem
(CSRSS), is compromised. Security can no longer be guaranteed. Because
Win XP can't run without Winlogon or CSRSS, this is one of the few
situations where the failure of a user-mode service can cause the system
to stop responding. This Stop message also can occur as a result of
malware infestation or when the computer is restarted after a system
administrator has modified permissions so that the SYSTEM account no
longer has adequate permissions to access system files and folders.

What is your computer make and model?

Do you have data you need to recover? Is the computer you are posting
from yours and is it a laptop or a desktop?

Have you tried Last Known Good Configuration?

Hi Gerry

You seem to know what you are talking about.
I have a pc with the C000021a fatal system error.
The only thing which was changed with this pc was that automatic
updates were enabled, and it seems that since MS have "updated" my pc
it is no longer usable in any shape or form.
The pc is a Dell Inspiron 510
Yes I have data I wish to recover.
No I am posting from another pc - the damaged pc does not functiion at
all.
All the MS knowledgebase artciles assume you can either access Windows
or at least access Dos. I can do neither.
Last known good config doesn't work.
Repairing Windows from the XP restore cd doesn't work.

Any suggestions?

Anyone???

G.
 
Thank you Mr Pacemaker

I think what you are saying is that if I take my pc apart, bare the
guts of it to the operating table and perform surgery on the hard disk
I *may* salvage some information off the hard disk.

Well forgive me if I feel somewhat short changed by this offer that
indicates that perhaps if I work really hard I may be able to salvage
something from my beloved pc, which is really all I can expect after
it has been "upgraded" by the mighty flipping Mircosft.

Oh you are of course correct, the pc is at least four years old so all
I can really expect is that it is only good for the scrap heap.

I'm f**king disgusted by this.

Cheers Bill.
 
I have the same error as above. I have been searching all day to find some
help. I have no help yet. I am using an XP disk and using the Repair option
to get to DOS. I cannot log into the system at all...ever. I am using an old
Dell Latitude D520 laptop with the SP2 installed. It a friend of mine's
computer who needs to keep some of the programs on the system because she
does not want to pay for more MS software.

Thanks

Unfortunately, because you've chosen to not quote any of what you've replied
to, I have no idea what is referred to.
( I have a Dell desktop, it was originally Windows ME then upgrade to
XP home edition)
Click to expand...

Then the machine is at least 5 years old. You may wish to upgrade the
entire system: I regularly purchase used but quite good name-brand desktop
systems (no monitor) for under $200, with valid XP Pro licenses and probably
more memory and significantly better performance than yours can have.
I am in the same position as one of the previously frustrated people in
which I get a blue screen and can't do *anything*.
Click to expand...

Actually, you can, it's just that you lack the parts or other systems to
take the steps.
I can press F8 and get to Windows Advanced Options Menu but when I
select any of the options it just goes back to the blue screen. I can
also press F2 and get the the Dell SETUP but not sure as to what or if I
can do here.
Click to expand...

The Dell Setup is known on other machines as the BIOS. It will have little
to do with the error you're experiencing.
Another previous post stated "Simply remove the drive from your system,
and attach it to the other system either via internal cabling or a USB2
drive case (about $20)." How do you do this?
Click to expand...

Get a case or adapter from a store, remove the drive from your system,
attach the drive to the case or adapter, plug it into another system. The
meaning will be quite clear when you have the parts in front of you. You
may wish to have someone help you with this.

It sounds like you will spend more time trying to fix this than doing a
reinstall. Back up, or get another hard disk and remove the original disk
and set it aside for later use as your backup, and do a new install. If
the hard disk is the original, given that the machine has to be at least 5
years old, it's time to replace it for reliability reasons. A new disk of
similar size should cost around $60. After the install is complete, attach
the old drive to the internal cabling as a secondary drive, and copy your
data back over.

You are making assumptions as to the cause of the problem. You need to
provide more background information as to what happened before the
problem first occurred. Some event usually triggers a problem of this
type. Did you make any changes to the hardware or programmes installed
on the computer? What are your anti-virus and anti-virus and
anti-spyware arrangements?

I see I posted to one of the threads where you have read the comments
that resulted in your questions. However, whilst failed memory and a
failed hard drive can cause your problem there are many other reasons
for this type of failure. You can get clues by observing the text on the
screen and listening to the beep sounds during the boot process before
it fails. Unfortunately it takes experience to know what you are looking
for and the text is only there for a brief moment.

Before embarking on measures to fix the problem is important to know
whether you have important data files you need to recover. If yes these
need to be recovered first. Do you have access to a second computer? Is
that computer a desktop or a laptop?

What exactly do you have by way of a Windows XP CD? What is your Dell
model. Some Dell models have problems with capacitors! Are your keyboard
and mouse wired or wireless?

Try booting with all hardware peripherals disconnected, except keyboard,
mouse. and
monitor.

A copy of the Stop Error code might help us.

Disable automatic restart on system failure. This should help by
allowing time to write down the STOP code properly. Keep pressing the F8
key during Start-Up and select option - Disable automatic restart on
system failure. Do not re-enable automatic restart on system failure
until you have resolved the problem. Check for variants of the Stop
Error message.

Charyl:
There are any number of competent contributors to this newsgroup who are
probably able & willing to help you resolve your problem, but you must
provide sufficient details & background information about your problem & the
system you're working with so that you can get intelligent responses.

With that in mind...

1. Precisely describe the problem you're encountering. Is this "Blue Screen
of Death" you refer to displayed during the boot process?

2. Are you ever able to boot without incident to a Desktop?

3. Does this BSOD appear later after bootup? Does it appear only when
shutting down your PC?

4. Did the problem arise "out-of-the-blue"? One day the PC was working just
fine; the next day the problem arose?

5. Do you think there's any chance that your problem is being caused by some
sort of virus? Do you have an anti-virus and/or anti-malware program
installed?

6. Do you have *any* clue why you're experiencing this problem?

7. What is the make/model of your Dell machine? It's a desktop machine, yes?

8. Do you have an XP OS installation CD? What version? If you have such, is
it an non-branded OEM or retail version of the OS installation CD? Or do you
have only a "restore" or "recovery" type of CD provided by Dell?

9. Does your current XP OS (installed on the problem PC) contain SP2 or SP3?

10. Since you're obviously able to communicate with this newsgroup, you have
another PC at your disposal? What kind? Desktop? Laptop?

11. Can I assume you're basically unfamiliar with a computer's hardware
components? Have you ever installed a hard drive (HDD)? Or an optical drive?
Or a graphics/video card? Ever been inside a desktop PC's case?

12. If worse comes to worse and your system cannot be returned to a
bootable, functional state, would it be acceptable to you if it was possible
to access data on the HDD and you could at least copy the data (presumably
personal data) to some other media? Or do you have a reasonably up-to-date
backup of your data?

13. Do you have a USB HDD external enclosure? Are you aware of such a
device?

The above is just representative of the kind of info you should be
providing. Feel free to provide any add'l info that you think might be
useful to someone trying to help you overcome your problem.
